CANON EF 200mm f/2L IS USM

The Canon EF 200mm f/2.0L IS USM Autofocus Lens is an ultra-fast
telephoto, is an honored member of Canon’s legendary L-series
lenses, has optics designed for optimum image quality. It uses
fluorite and UD lens elements for excellent chromatic aberration
correction and consists of 17 elements in 12 groups. The built-in
Optical Image Stabilizer gives it up to 4 stops of stabilization
correction. The inner USM and optimized AF algorithms result in
fast and quiet autofocusing, and the circular aperture can even
produce beautiful out-of-focus images. This
ultra-high-performance lens also improves its durability – better
dust- and water-proofing. The EF 200mm f/2L IS USM is outstanding
for many available-light applications, including indoor sports,
theater work, fashion, and candids at events.Features: Image
